My Farm Is Connected to Ancient Times

Zhang Qing, who had had enough of studying in the big city, chose to go home and lie down, and unexpectedly discovered that his bankrupt small farm had an arbitrary door leading to ancient times. Since then, Li Ping's life has undergone earth-shaking changes. On Monday, I brought potatoes to Zhuge Liang to exchange for gold. On Tuesday, I went to the Northern Song Dynasty to sell high-yield corn. On Wednesday, I was kidnapped by Li Shimin to plant cold-resistant cotton... The horseshoe gold of the Han Dynasty, the best ginseng king of the Northern Song Dynasty, ambergris of the Tang Dynasty, etc. Are like crops. One crop after another grows from Zhang Qing's farm. Late at night, one after another rich men knocked on Zhang Qing's door: "Please, Boss Zhang, sell me a piece of divine ginseng king!" "Master Zhang, please provide more wild rice as a tribute from the Song Dynasty!" "I'm from the research institute. Please ask Boss Zhang to provide some more rare plants for us to study."
